SiliconDust HDHomeRun Flex Duo 2 x ATSC Tuners - HDFX-2US

Works great with the native iOS and Roku apps, but you will get crashes on both of them when viewing channels where actual RF signal strength or noise is an issue... That being said, it's a great and easy to use device that so far has operated flawlessly when RF signal has not been an underlying issue. I presently use the HDHomeRun tuner device to provide OTA HD streaming to devices and televisions on my home network. The device is located out in my unconditioned barn where the outside roof mounted antenna has a strong signal for all the major network stations I need (mainly for sports). It's connected via underground fiber back in to the home network. (During testing, I actually powered it via PoE with an external adapter while searching for the best location across my property, and it operated without issue by that means as well...) Originally, I did have the same Roku app crash issues mentioned in other reviews, but I was able specifically chase that back to one VHF channel (12.1 at 189.029mhz) with a very high S/N ratio (likely from my outside POE cameras) that would ultimately cause the data stream to be interrupted and crash the native Roku app, but only in that scenario on weak channels. Pointing your web browser to the device provides an intuitive simple interface for configuration and setup. This made signal troubleshooting a breeze by showing strength and s/n readings live for whatever given channel each tuner was parked on. (Handy to look at on your phone while you're making fine antenna adjustments on the rooftop). You can directly access streams via url (for example from VLC) over the network, which will automatically assign an available tuner to whatever channel you're attempting to access. In the end, my production setup has the HDHomeRun fed into TVHeadEnd server that pipes it to Jellyfin (all on the same Linux machine) so OTA TV is available everywhere it's needed. The key here in this setup solves the marginal channel issue for me-- TVHeadEnd service gracefully handles any weak signal issues or interruptions (weather, lightning) before they ever get passed down the line so the video stream never actually crashes. Again, it's my work-around and unique situation that I had fun making work... All that being said, just buy it- you'll be glad you did!

Works well. Using it with the PLEX DVR, so can't speak to the attached drive or Channels DVR options, but it is doing the job. The DVR records the shows to my NAS. I have been happy that setting up the recording has been easier than I expected. For example you can set up to record just one show like a soccer game, or all similar soccer games. Setup was easy, I connected it to my router and to the antenna. It picked up a bunch of channels, but it is definitely more selective than my LG TV's tuner. Now that I have it working well, I am thinking that having more tuners would have been useful.

We cut the cord a long time ago and we stopped watching anything broadcast because, without cable, we didn't have access to DVR things. Without a DVR, we would have to slog through commercials, and we'd become accustomed to binging things without pause. We honestly didn't miss anything and it was almost like our lives became lighter once we weren't tied to some antiquated idea of "primetime network TV". There were a few good shows that we wanted to watch, but they were usually on Hulu, so it wasn't a big deal. Then, once the networks started feeling the pressure, they started to shun Hulu more and more until there were some shows that you couldn't watch unless you subscribed to one of the big 3 networks overpriced streaming services that were a vain attempt to maintain the old order. Thanks to Amazon Prime, Netflix, and Hulu -- we figured good riddance to networks. But there were still a few shows that we wanted to watch that we knew were broadcast, but we still weren't going to watch them with commercials. Not because the idea of commercials is awful, but because of the time involved. Without commercials, a half-hour show drops to 20 minutes. And you can watch an hour-long show in about 40 minutes. Your don't spend your time watching commercials for things you're never going to buy because of the shotgun approach to advertising that is still pervasive. This little device solves those problems. First, there are 2 tuners on this, so you can record 2 channels at the same time (or watch one while the other is recording). To be clear, this doesn't include a DVR, but if you have a network attached storage device (NAS) for your network, then you can hook this up and have the equivalent of a DVR. There are a few downsides, but mostly trivial to figure out how to "fix". One is that it's not easy to know the time when something will be aired without the old cable-box "schedule" menu. This device has a subscription that you can get for a really low yearly price -- or you can get the same thing for free with a little research and creativity. This model only has 2 tuners, but there are others by the same company that have 4 tuners and ones that have built-in hard-drives that will actually function as a bona fide DVR for OTA broadcasts. The main thing you'll need to get in addition to this box is an antenna. There are lots out there and some are better than others so it pays to do a little research. The other thing you'll need is a working internet connection so that you can get the program guides in order to know when "your show" is going to be aired. By itself, this isn't going to impress anyone because it doesn't do anything that a regular TV can't do. This is basically a special purpose device which you need to combine with other devices to get the full potential. I was really surprised by the sheer number of channels that are still being broadcast. I guess that the great cord-cutting exodus left a void that was filled by very cheap distribution by over-the-air. Most of it is still hot-garbage as it always has been. Infomercials, really bad local access shows made by nearby universities. Tons and tons of local annoying commercials, bad network news shows that seem to somehow still be hanging on with whatever life-support is still keeping them viable. The coolest part that we discovered is . . . wait for it . . . Reruns! About a third of the 45 or so channels that we can receive all contain tons and tons of reruns -- with lots and lots of commercials to be sure, but the reruns are from things that you won't easily find on the streaming services. Like the original Twilight Zone comes on two or three episodes back to back every day. You can probably find it to purchase as a whole series, but it's hard to justify purchasing that when you have so many other shows that you could buy. DVD's are pretty much dying out, too. This is quite a bargain for what it is and for what you get. It's very inexpensive compared to buying a whole TV and with 2 tuners. If you're here looking at this item, then chances are you know what you're looking for already, but if you're just browsing and see this, make sure you know what it is before you buy it. It's not magical by itself, and it isn't going to solve a problem if you're not looking for a solution already. What this does is allow you to expand your current "range" of available options that currently exist and do it without adding yet another paid streaming service to your budget. If you are also here intentionally looking for this kind of device, I'll give you a few answers to the questions you might have. It's one of the best ones that I've found for the price and performance. It works well as a tuner and their paid service works well if you don't want the hassle of DIY for the program guide. Removing the commercials from the "taped" shows works very well with the shows I've tried so far so that even removes the need to fast-forward through commercials. It's fast enough and works great for recording 2 shows at once -- no glitches. I can only confirm that it works well with Synology NAS. I have the 220+ model and it's more than enough. Depending on your goal, this model might not be enough. This is the lowest end in the bunch -- and it's even being replaced soon with a more powerful version. But for the price, this is the best and most compatible one that I've found. I'm sure there are better, but not many that could hit this price point. This has been a great addition to our home-entertainment infrastructure, if you will. If you don't want to spend a ton on the over-the-air part of your entertainment flow, then this is for you. Broadcast TV is still a vast wasteland of raw sewage, but every now and then something worthwhile can be found drifting along that pays off. Overall, highly recommend this and other devices by this brand. It's easy to use, it's very small, and runs surprisingly cool for a device with this much packed in. Five stars.

I've owned and used a tablo duo and an AurTV 2, they worked with some problems. I live 38.5 miles south from the TV tower in San Francisco in north San Jose. Right next to a busy commute hiway. I have an RCA digital Antenna on the roof. So, the tablo had reception problems, dropouts resulting in things getting out of sync and distorted audio. The AirTV did better, but also had drops and watching live sports the video would get jerky (buffering I guess due to signal problems). After reading reviews for this device, decided to give it a try! So the tuner in HD homerun seems better then the Tablo and AirTV. Drops with this device results in picture freeze but still get audio and when the picture comes back, it's in sync! This is far superior result over the competition. Less drops, no audio problem, gets back in sync. PROs: it works like it should! Was easy to install and get up and running. It's a simple, no frills OTA streaming tuner. CONs: instructions, documentation to update (it needed one) non existent. What hard drives can be used, no list. How to install, format hard drive and open account for DVR, none really. They seriously need a tech writer to write up instruction, directions. I'm a techy person, been using computers since late 70's, used to do some phone support for dial up modems. I had to write an email to tech support to get information and instructions. Hard drive: and flash drive, hard drive, solid state drive over 500 mb should work. Update and hard drive format: this device works with phone, tablet, FireTV, Roku and other devices. The setup install though, should be done from a PC or laptop! After hooking device up to your router, use a PC on same network and go-to: http://hdhomerun/local ( you may need to clear browser data). That should pop up a menu for setup, update and later hard drive format. After formatting go to hdhomerun store and open account. There's a link to link your device to your account, but that didn't work for me! Write down the 1st 8 digits of the key for the account, go to settings and then account in your hdhomerun application and input the email for the account and use the 8 digits to key it. That information I couldn't find anywhere on their site or anywhere on the internet. I would have gave this baby a 5 star rating, if it had these simple instructions on the setup guide! I'm giving it 4 because it works well! One other note: seems they intended this for PC (mouse, graphical user input) which works well on touch screens. But I watch mostly on my TV using a firestick. No mouse, no touch screen. So, navigation is a tad clumsy, a little slow compared to PC and phone. Takes a little getting used to. The DVR menu is basic, but works well enough, no frills. No commercial skip, no preview when fast forwarding or rewinding. Appears to be no way to set up recording series of program. Just find what you want to record, and select it. Recording will start 30 sec before and end 30 sec after. Gets the job done! All in all, very happy with it so far. Hopefully features will be added down the line. Value for the money, excellent, support good.

This is a further update to the review below, written Apr 13, 2025. I contiinue to be impressed by the HDFX-2US and the Silicondust customer service. I experienced another failure of an HDFX-2US under warranty, and customer support sent me a new unit with reasonable quickness and minimal inconvenience on my part. I've had several of these devices fail now, but customer support assured me that they've made changes to their low-noise amplifier's input protection, which should make failure much less likely. *** end of update Apr 13, 2025 This is an update to the review below. The main update is to add that the unit I received failed after about three weeks. As I mentioned, I have owned more than one HDhomerun that failed, including at least two that were under warranty. I can definitely say that the warranty support is still outstanding, and I received a new unit within days of reporting the failure. **** end of update. This is a review of the Hdhomerun model HDFX-2US. Its basic function is to accept TV signals from an antenna and make them available in a format that can be streamed by devices on your home network and displayed on a screen, anywhere there is access to either wired ethernet or Wifi. This model has two tuners for channel selection so you can stream two TV channels at once. If you pay a monthly fee you can also access DVR functions. There is a USB port that can be used for external storage. I believe network storage is also supported. SiliconDust provides an app on many platforms to which the HDhomerun can stream directly. Supported platforms include Roku, Android, Apple products, Windows, LG WebOS TV, etc. I've tried the apps on Android and Roku, and found them to be adequate. Third party software also supports the Hdhomerun, like more comprehensive home theater applications. I use Kodi on Libreelec, but there are others as well. Note that HT applications (e.g. Kodi) may provide a free DVR function A note on setup: At various locations the instructions tell you to access the maintenance functions by connectiing to a web page at either my.hdhomerun.com or homerun.local, neither of which worked for me. I was able to connect to the device by specifying its ip address on my local network. I.e. http://x.x.x.x where x.x.x.x is the device's ip address. Once connected, I downloaded a firmware update, and there are other functions like editing the channel list. Overall, this is an excellent product. My only reservation that prevents me from giving it 5 stars is that I've had a few Hdhomeruns of various generations and none have lasted especially long. On the other hand, I believe the current product has a 2 year warranty, and, as I recall, my experience with warranty return has been painless. As far as overall function, it is fine. I receive dozens of channels and the Hdhomerun provides a stable connection. However, I have a rooftop antenna and live in a major metro area, so YMMV. Note also that this model isn't compatible with ATSC 3.0. It is also not compatible with encrypted cable signals.

What happens when internet is out or the or SiliconDust service is shutdown or discontinued? YOUR DEVICE BECOMES A USELESS BRICK! WHEN INTERNET IS OUT, THE NETWORK-TUNER CAN'T CONNECT TO HDHOMERUN SERVERS FOR TV GUIDE AND IT CLOSES THE VIEWER APP REFUSING TO FUNCTION LIKE A REGULAR LAN ONLY TV TUNER. HERE IS ANOTHER DEVICE THAT DEPENDS ON INTERNET CONNECTION/CLOUD TO FUNCTION EVEN THOUGH THE ANTENNA AND LAN IS ALL THAT IS NEEDED TO STREAM THROUGH LOCAL NETWORK. THIS IS AN ARTIFICIAL LIMIT AND CAN BE FIXED VIA A SOFTWARE UPDATE BUT THEY PROBABLY WON'T BECAUSE THEY WANT TO RUN A BLACK BOX IN YOUR HOME LAN AND COLLECT TELEMETRY. WILL BE RETURNING. DO NOT BUY. ========================================================== This Network Tuner is outstanding. I have the signal split from antenna to a decent quality TV among top tier model, and to HDhomerun. Performed side by side comparison for some channels where TV pixelates, HDhomerun is broadcasting the same channel clear without artifacts and watching it on a tablet/firestick/laptop/cellphone. The install was super simple, download the app, just plug the cables in and play. HDHomeRUN hits a home run in performance. I was under the impression that it would be doing multicast, meaning multiple devices could watch the same channel without taking up tuner space but that does not seem to be the case. Regardless, it is well worth the price and in my opinion much better performance/value than TABLO even though recording is not included with HDhomerun . Tablo seems to be transcoding the native broadcast to MP4 from MPEG2 in order to reduce network traffic but it slows down, image quality degrades where HDHomeRUN is retaining native broadcast resolution and encoding MPEG-2. Even with my older wifi I'm able to watch it smoothly. Did I mention, it works great with FireTV stick (4k), Fire Tablet, desktop, laptop, and phone,.... It just works!

I only give five stars and take my time to write detailed reviews when something is deserving. And you should buy it. In this case, this little piece of tech has far exceeded my expectations. The reason for that is I have a first generation Haupage, and I have never been able to get more than a couple of channels. I've been in the tech world over 40 years, am a Broadband and Network Engineer going back to 2001, and cut the cable about ten years ago. Biggest problem, without paying fees, is real time news on TV. Yea, you can get real time local news streaming (For a fee in our case) or watch it on a computer, but we do prefer having it on TV. There are also some network TV shows my wife likes, streaming they are always a day late. She would like to watch them when they are on. And this device was the ticket. I watched quite a few videos on how to get the best reception with this device. In short, 45 miles away on a single hill with multiple towers, they broadcast 40 channels. As noted I was never able to get more than 2 or 3 even with the most expensive powered antenna. My RV has an integrated raise. Lower antennae and can get 8 from my backyard. After connecting this device, properly, I get all 40 channels crystal clear. I bought this device fully expecting to see it not work and send it back. Nope, definitely keeping it. Here are step by step instructions, I took from multiple videos, on how to get the most channels and best reception. But first a couple of notes. After setup, I will go over some of the features of this little box and the app. You can ignore some of the older review complaints, because as I learned (Again watching videos) there have been more than a few updates and I can verify you do not need a Plex server or anything else. More on that after installation. I have a hardwired house with a network room, server, couple of cabinets etc, so for me I can make it work anywhere in my house. I am not restricted by a modem/router. I will make some notes on that as I go along. 1. Find your broadcast towers. There are multiple websites you can use, I used Channel Masters and two others to get exact location. I found that 40 channels were broadcast from a hill in one city and 3 more were broadcast within range from a different direction. I cannot get those three channels. It doesn't matter because I get all the local and networks on the 40. 2. Download a map compass on a cell phone. I used an app called Compass Maps for Android. You may or may not have to download the map in addition to the compass. I did, works great, going to keep it. That is unless you already know the exact location of your broadcast towers. 3. Locate the window in your house closest to pointing directly at those towers. A couple of notes. * Walls will severely restric reception. * Clear glass is good, this will still work if you have screens, but screens will restrict reception. In a storm window with a screen, I recieve about 15 of the 40 channels available, moved over one window, center, no screen, 40 channels. 4. If you have an amplified antenna, do not use the amplifier. Thread the antennae directly onto the HDHomerun. Amplifiers severely interfere and restrict reception through the tuners and are not needed. And of course if you do not have an amplified antenna, don't buy one for this, not needed. 5. Thats it, for best reception put your antenna in a window facing as close as possible in the direction of your broadcast towers, plug it in to your network or router. Then download the HDHomeRun App on any or all devices. Note that this should be obvious but two tuners means you can only watch on two devices at once. But you can set it up on as many devices as you want, in my case it is set up on nine devices, including multiple big screen TV's, several computers and a couple of cell phones. It works perfectly through all of them. This works through any type of network configuration, wireless router (with jacks), hardwired home network or Powerline Adapters, I have netgear powerline adapters running in a couple of rooms off of my network and tested, works fine, no problem. The App I nearly ignored the app based on old complaints until watching a video that showed the complaints had been addressed. It is not hard to use and has a lot of new functions. (I do not know how the old App was since I have not used it, so I have to take other people's word for it). Once you download and install the app on your Smart TV or streaming device you use your normal remotes as usual. There is no separate remote for this device. You do not have to create an account to use the app, and there are no fees for anything. Once you click on the app you will see: Version (You do have the option to upgrade firmware through your account. I did that) Using ASymch Platform API It searches and then "Found 1 Device" Then device number and HD Homerun" followed by booting to the main screens. Total boot time for my devices is no more than about ten seconds. It will boot to the last screen you were watching, including if you logged out while watching a channel/TV program. Your first screen is your "Live Screen". Pressing theup or down arrows on your remote displays all of your channels and moves up and down through the channels. It may take a couple of seconds to populate all the channels. On the right side, all of your channels, each channel shows what is currently playing on that channel with a screenshot along with channel, 3.4, 3.3 and so forth. On the upper left side of the screen it will show time, Channel and current TV show playgoing. on the very top right of the screen are five icons. Search, favorites (Star you can click to lock that channel/show as a favorite, return to last icon, a newspaper icon that bring up only the news channels, a football icon that brings up only the sports channels, and a movie (film) icon that brings up only movies. Bottom is your fast forward, reqind, pause (You can fast forward, pause and rewind live TV with this app), your SAP, CC, Zoom, full screen and "Discover" Icons. Hitting the Discover Icon takes you to the Discover Page which is a full screen guide of TV shows, movies, sports, news, documentaries etc., you can select any of them, select a time when they will be on and set to record. Note you do not need an account to record, you can attach up to a 2TB drive to this device for recording. Above the full screen guide are four options. Now (Which it will be on automatically), Shows, Movies and Sports and clicking any of them will show only those categories in the guide. Above that are four options. Live, Recorded, Discover and Tasks. Live takes you back to the main page where you can watch whatever is on live TV. Recorded is self explanatory Discover shows you the guide with everything that plays on every channel. Clicking on any show, sports event, or whatever gives you the option to record an entire series or multiple events. Tasks shows whichever tasks you have selected, Record, playback and others while an "Upcoming" shows just that, upcoming tasks. Clicking "Live" at the top of any screen other than the main "Live" screen takes you back to the live TV screen. Note on the top right corner of any screen other than the Live screen is a settings icon. In the settings you can do the following. See account information See devices and device serial number See a list of all available channels and select any number of them to add to favorite channels Set parental controls including adding a Pin Set your Start Page to any channel you want on bootup The guide on the Live page is called the Live TV slice guide (Ill explain further down), you can turn it on or off. Set your speaker configuration. There are multiple surround sound options, Digital Passthrough and others Send Diagnostic Information (On/Off) The very bottom is early access to new features. For me, I am keeping it off because have seen more than one person get a firmware update and brick their device. The Live Slice TV Guide on the "Live Screen". On your remote, you use the up and down arrow buttons to open the guide and right and left arrow buttons to see more information for whichever channel you are watching. Clicking right on your remote arrow key will show you the next 1,2,3,4 and 5 shows coming on, on that particular channel, with a synopsis of the current show and a synopsis of the next five. You can click to see 1 through 5, whatever you want. If you click on any future show, it will give you the option to record that show. Clicking the left arrow button closes the guide to the show you are watching. To clear the screen of the Live Slice Guide, simply click your back button. How satisfied am I with this device. Solid Five Star satisfied. Easy to set up Works great with any type of network Uses basic antenna's, no amplified antenna needed Crystal clear picture Great app with a lot of options Can connect up to a 2TB hard drive. Quick Edit: When I first purchased it recorded without an account. Then it stopped and I had to add an account and purchase the annual subscription. The subscription IIRC is $27 (give or take a few dollars) annually and worth every penny. On the original recordings I really had no control over it and could only delete directly from the drive. Having the account with the DVR service gives me full control and makes the low cost annual fee worth every dime.

Works well for cord-cutters if the antenna gets good signal. HD picture is great, UI is intuitive (we use it with an AppleTV), and it can be setup to start on the same channel last viewed (like a regular TV). Only negative is that it started freezing a few months ago. It was okay for almost a year, but now it freezes once or twice an hour. Tech support says it looks like it temporarily lost signal. I have Verizon fios gigabit with a wired Ubiquiti AP in the same room as the AppleTV, and I don’t see anything in the Ubiquiti logs that would indicate hiccups in signal. Annoyingly, the HDHomeRun does not just restart the video like your phone would if you had poor cellular signal. You have to click on a few different things with the remote to get to going again. Because of this, we’re testing a live TV streaming service. If future updates don’t resolve the freezing issue, I may get rid of it.
